Radical Katana Assault
For the Radical Katana Assault Radical has taken the biggest backend ball they have made to date and they added a flip block to it. They took this same ball and wrapped it in the revolutionary skid snap coverstock, the HK22 - HyperKinetic Pearl. This core and cover pairing results in a quick response to friction on the lane as well as lots of continuation through the pin deck. Radical considers this ball a "monster flip ball" that is meeting a need the bowling world has longed for.

Bottom Line:
Yes, I would recommend this to a friend
Smooth, and reliable
Drilled 45X4.5”X35. This Ball is very versatile. I can play any angle and line I would like to, without any worry about my carry angle. The smooth motion really fits well with the continuation of the HK22 Cover. This ball is good on the fresh, and even better on the burn. It lets me open my angle and still allow the ball to continue through the pins. Really love the Katana series, and glad to see this ball out on the market. This is a must-have ball in your arsenal.

Monster flip!
Stats: PAP 4 over ¾ up, 15 mph, 18 tilt, 275 revs. I drilled mine 60x3.5x20. Designed for massive flip on the backend, this ball will not disappoint. For someone with average to lower revs like me, this ball provides a lot of help on the backend, recovering from parts unknown when I miss. This ball works best for me on medium oil conditions. Do not be afraid to get it out to the friction!

Katana assault
Katana Assault
I’m a left handed bowler. My ball speed is around 14.5 mph. My Rev rate is around 275 rpms. I recently drilled the this ball. I’m layout choice is layout B (45 x 4 x 35). I think is ball is great. I use this ball for my first two games in league ( house shot). This ball is very quick off the spot at the break point. I’m amazed by how well it carry the pins. With Hk22 cover it is very clean through the fronts. And with its dual density core makes it continuous through the pins. Great job Radical Bowling Technologies. Another great piece of equipment.
Thanks,

Katana Assault
I went with a 40x4x30 drilling. My speed is 14.5 and low rev rate. The original Katana has always been one of my all time favorite balls so I was very excited for this one.This ball is very clean, gets down lane longer before making that monster hook into the pins continuing through the deck. I use this ball on medium oil lane conditions and see very little transition only needing to move 3 to 4 boards over a 3 game period.

Katana Assault
Katana Assault is a very versatile piece. I have not thrown the original Katana, but after using this, I found out what the hype was about. This ball can glide through the lane and make a quick transition off the oil pattern. It can play straight down and in if needed and can hook the lane while carrying the corners out. Continuation through the pins is not an issue for this ball. Misses right tend to pick up and make the corner to the pocket, and misses in will glide through the oil and pick up at the right spot to carry. This ball is a must for your arsenal when you need a big pearl asymmetric.
By James from Maine
Pros:
angular, big asymmetric pearl, medium to heavy oil patterns
Cons:
heavy volumes and flooded heads
Best Uses:
benchmark asymmetric pearl, medium-heavy patterns

Radical Katana Assault: Adding to the legend!!!
Radical Katana Assault Review
Stats: LH: Speed – 17.0; RPM – 350; AT – 19; AR – 55
Layout: 45 x 5” x 65
Radical’s newest Top Shelf launch, the Katana Assault, is a newly engineered version of the legendary Katana series of balls, featuring several improvements that should surely get lots of attention. The Katana Assault and the new chemical compound cover known as HK22 Pearl create a new level of backend reaction. This is a Katana on steroids. I chose the layout I did to get the ball to roll forward a little sooner due to my slightly higher tilt but transition a bit slower to really utilize that longer, stronger roll phase of ball motion. I have used it on a couple of different patterns and here is my assessment:
42 ft. THS (typical house shot): The Katana Assault has been a very strong, yet predictable ball for the house shot in two centers I frequent. What I love about this ball is that it can handle decent volumes of oil, makes a quicker defined move off the spot, but is still predictable enough to control from shot to shot. Very versatile to cover changes, I took mine from box finish, down to 1000 and back up to 2000 polished, and it responds to all of those very well. If you are seeing too much early hook, take the cover up to 3000-4000, too much length, just sand it to 1000 or even 500, it takes to those changes extremely well! Do not be afraid to adjust the surface to your game, this ball can handle it!
36 ft. Viper pattern: I roll on this pattern every Tuesday, and the Katana Assault was the best ball in my bag on the fresh, alongside the Bigfoot Hybrid. I could play further in the sauce with the Katana Assault compared to the Bigfoot Hybrid, but they played off of each other very well. Projection and speed control are key on Viper, and the Katana Assault at 3000 was the perfect matchup. It rolled forward perfectly and hit heavy through the pins, carrying the off pocket hits extremely well. As the night progressed, I was able to move slightly further inside, roll the ball firm off my hand, and it saw the friction consistently, making my moves easier and more trustworthy, resulting in higher scores and more confidence in the ball.
If you are looking for that quick responding, heavy rolling ball all the way through the pins from a high end asymmetric pearl, look no further than the Radical Katana Assault. Available now from Bowler Builders Pro Shops, and at pro shops everywhere! Join the Radical Revolution today!

Best Katana Yet!
Fantastic ball once the lanes break down. This ball goes long and snaps hard on the backend once the lanes break down. If your a Radical guy like I am this is a must have addition to your arsenal. Mine originally went a little too long so I took it to 2000 abralon and it faced up on the pins much better. Very versatile ball, can change surface to whatever conditions you are trying to use it on.

any

A ball designed for all styles. As long as you have friction, this ball is better than the original.

Katana Assault
So, I decided to punch the new Radical Katana Assault. The Katana Slash made some telecasts back in 2018...pre EBI acquisition. The Slash originally looked like a good piece. With the new Katana Assault having the HK-22 additive in the cover coupled with my liking the Defender Hybrid with the HK-22, I figured I would try one.
I decided to do a little weaker pin to PAP layout as I've been drilling most of my stuff in the 4 3/4- 4 1/2 pin to PAP range. I went with 45 x 5 1/2 x 25 and threw it at box surface which is Crown Compound. The shot I tried the new Katana Assault was on left over THS. The ball appears to be pretty quick off the spot and definitely makes a pretty defined move on leftover THS. My sense is, from what I see, is this asymmetric core release will be best on medium to longer distances or definitely on broken down patterns where you need a little cleaner look through the front and a stronger down lane change of direction. Overall, from what I have seen on social media, the new Katana Assault is getting many positive looks!
The Radical Katana Assault is readily available. See your pro shop for more information.

wow this one is strong
I drilled my Katana Assault 45 x 4 x 35 as I wanted something stronger. This ball is pretty amazing and defiantly a different motion for my arsenal. The ball is a polished pearl and yet it picks up the mid lane very very well. I did not expect the back end and continuance that the ball has, specially with the shorter pin to pap. I hit this ball with a 3000 pad and it was perfect! This is my first Katana and all I can say is WOW

Favorite core with favorite cover
I loved my original Katana. Now with the new HK22 cover, it is back, and better than ever. Being a Hybrid, it fills a gap between my Top Speed and my Black Widow Ghost. This ball fits perfectly in my arsenal.

katana is back
The Katana Assault is a huge pearl ball wit the HK22 coverstock. it is great on fresh and just a good overall continuous hook. this ball rolls a little early for me they way i layed out the bowling ball which i need in my bag right now.

Katana Assault
Once again putting the HK22 Pearl cover on a Radical piece has raised the bar in expectations. I drilled mine pin down as I wanted to add an asymmetrical pearl to my pin down bag. I have only had the control given by the pin down layout in the Max Results. This ball is exactly as expected smooth and strong through the pins. The HK22 cover gives that special punch on the back and carries the slight misses much like the Bigfooot Hybrid. Love this one and I will be getting another for a pin up layout!

Radical Katana Assault
The Radical Katana Assault is a nice option to have in the bag. It has the new HK22 cover-stock that blew me away in the Brunswick Defender Hybrid. The Katana Assault is a little cleaner getting down lane a bit farther than the Defender but has a stronger, more defined change of direction off the friction. It goes through the pins very strong. If you like having the head pin fly off the wall, this is your ball. They only give me 5 Stars to work with, but I would say it's a 4.7 star rating.

How does the Katana Assault compare to Black Widow Hybrid?

Question:
How does the Katana Assault compare to the Infinite Physix?
Have an answer to this question?
Answer:
The Katana Assault and Infinite Physix are both high performance balls for heavier oil conditions and both have a pearl reactive coverstock. The Katana Assault however has a smoother compound finish to help give it a slightly later read on the lane and will have a slightly sharper hook on the backend versus the arcing hook that the Infinite Physix has.
